Puzzle Studio is a game Chuck Sommerville was developing due to legal difficulties in releasing Chip's Challenge 2. Epyx Inc., the original publisher of Chip's Challenge, sold the rights to CC2 to Bridgestone Media after they declared bankruptcy. Bridgestone Media refused to release the game unless a large unspecified sum of money is paid. However, CC2 is planned to be released on May 28, 2015. Similar to the emulation of Tile World compared to the MS game, Puzzle Studio is meant to be a legal version of CC2, with different graphics, sounds and source code. A Puzzle Studio level in an incomplete game stage can be watched at the bottom of the page.
